At a first look at things, I would prefer a 7" Touch-screen, which I
think its big enough to let my fingers work on it during flight.

I have a fairly full panel in my Libelle: 80mm ASI, altimeter and SDI C4
for starters followed up by 57mm B.40 vario, T&B and radio.

Currently me navigation system is LK8000 running on a Medion S3747, held
in front of the panel in a fleximount: as its just a 3.5" (88mm) screen,
it doesn't hide any instruments. I find its touch screen is useable in
flight, but then I don't have big fingers.

I was wondering about touch screens because some of the RaspberryPi shops
(Pimoroni and ModMyPi) are selling 3.5"/85mm touch screens for around GBP
35. These tend to use I2C bus connections though I did spot one with a
USB connector.

Hi Martin,

sorry for late reply.
Of course I know the panel-problems, not only with the Libelle.
As I am verry much restricted in panel-space in my Banjo, and do do not want to exchange all my 80mm instruments by expensive 57mm instruments, I do look for a smaller and less difficult version. let´s call it a OV-Light.
5" or even 4" touchscreen, without stick-remote, gyro, accellorator and other additional functions. Just a plane Glider-Navigation to replace my old IPAQ with SeeYou running at it.
At this moment, I try to get a Light-Specification together with the designer-group, hope this will work.
On the other hand, I am just a dumm Electronic-Neandertal (greenhorn), so I have to work out first how to get the PCB´s manufactured and whats the special secret by soldering the SMD´s onto the PCB´s.
In the next step, I like to build a Light-Version to get builders-experiance, in order to document those things at my website UL-Segelflug.de, to make the doeing easyer for other builders.
Stay tuned at UL-Segelflug.de and watch for progress.

Best regards from Germany
